Chapter 2. Installation and Operation

RACKMOUNT INSTALLATION

The MX2800 STS-1can be mounted into a standard19-inchor23-inchequipment rack. Follow these steps to mount your unit into a rack:

1.Prepare the MX2800 STS-1mounting ears by scraping the paint away from the mounting ears’ portion that makes contact with the rack and the portion where the screw mounts into the side of the MX2800STS-1.

2.Install the mounting flanges on each side of the MX2800 STS-1at one of the three available positions.

Be sure to install the flanges with the screws provided.

3.After the flanges have been installed, position the MX2800 STS-1at the correct location within the rack and secure the mounting flanges to the mounting rails of the rack.

4.Make all network, DTE, and power connections to the rear of the unit. See Power Up on page 2-2 for more information on making the DC power connection.

5.Using the 8-positionmodular toDB-9female connector and the8-positionmodular to8-positionmodular cable, connect a

VT 100 terminal device to the CRAFT port on the front panel of the unit.

Two MX2800 STS-1smay be stacked with no spacing between units. ADTRAN recommends 1U (1.75") of separation above and below the two stacked units. This spacing allows the unit to dissipate heat. The design of the MX2800STS-1uses the chassis to distribute heat generated by the unit's internal cards. This design allows the unit to operate without a cooling fan, which increases its overall reliability.

Connecting the Breakout Panel

The optional breakout panel (P/N 1200291L1) connects to the MX2800 STS-1via theIN andOUT Champ connectors located on the back of the unit, and provides 28 RJ connectors for the individual T1s/E1s. Shipment includes twosix-foot,64-pinto64-pinAmp cables which allow direct cabling to the

MX2800 STS-1.Connect the breakout panel’sIN Champ connector to the MX2800STS-1’sIN Champ connector and the breakout panel’sOUT Champ connector to the MX2800STS-1’sOUT Champ connector (seeFigure 2-2).

Chapter 2. Installation and Operation

LAN Port

The LAN port is an8-pinmodular connector that provides a 10BaseT ethernet LAN interface. ThisLAN interface is used for SNMP and Telnet control.

Connect the LAN port to intra-buildingwiring only.

Modem Port

The MODEM port is an8-pinmodular jack that provides a telephone line (POTS) connection for the internal V.34 modem.

The MX2800 STS-1can be configured as adial-inhost and also as adial-out-on-Trapdevice (meaning the unit dials out to a specified host to report error conditions).

Information regarding the built-inmodem applies to the following list of numbers: 4200659L1, L2, L3, and L4.

Noncritical and Critical Alarm Connectors

The alarm connectors connect to the three contacts of a Form C type relay on the main board of the MX2800 STS-1.This relay is activated any time the MX2800STS-1detects an alarm condition on theSTS-1network interface. BothNC (normally closed) andNO (normally open) contacts are provided.

Connect alarms to one of the three-positionmodular terminal lug connectors (provided). These connectors make it easier to perform initial wiring and to connect and disconnect alarms when replacing

rackmount units. Once a modular connector is wired, push it firmly into the rear panel NONCRITICAL orCRITICAL connector.

The alarm functions can be enabled or disabled through the ALARM RELAYS section of theCONFIGURATION menu (see the sectionAlarm Relays on page 3-18).

Network Interfaces

The network interfaces are full-duplexcircuits provided by four BNC coaxial cable connections (two for each controller card). The receive data from the network is connected to the RX (IN) connectors, while the transmit data from the MX2800STS-1is connected to the TX (OUT) connectors.

Network interfaces must be connected using coaxial cables that have the shields grounded at both ends.

DSX-1/E1Interfaces

The DSX-1/E1interfaces are64-pinAmp connectors. These interfaces provide Tx and Rx connections between the unit and equipment such aswire-wrappatch panels,punch-downpanels, or breakout panels.

Connect the DSX-1/E1interfaces tointra-buildingwiring only.

Power Connection

The DC and AC power connections are described earlier in this chapter on page 2-2.
